Abstract:
The strength of modularity between perceptual visual-form
subsystems and conceptual/associative subsystems was examined.
After viewing complete words (e.g., bear) during initial encoding,
participants completed word stems (e.g., BEA) presented directly to
the left or right hemisphere (briefly in the right or left visual
field). Half of the target stems were presented in the same letter
case, and half in the different letter case, compared with their
corresponding words during initial encoding. All of the stems were
backward pattern masked. When the encoding task was conceptual
(like/dislike judgments), letter-case specific memory was observed
in right-hemisphere presentations but not in left-hemisphere
presentations, as had been found in previous studies without
pattern masking. However, when the encoding task was perceptual
(vowel counting), letter-case specific memory was not observed in
right- or left-hemisphere presentations, unlike what had been found
in previous studies without pattern masking. Assuming that masks
selectively affect perceptual processing at test, results suggest
that depth of encoding can influence perceptual memory effects,
belying strong modularity between conceptual and perceptual
subsystems.
